Layers appeared !

 by Kazu

 An active fault line and the cross section appeared in front of us on the trail to the peak of Mt. Tokachidake.

 It showed the years and the times of eruption of the volcano like the wrinkles on my face.

 Without sincere effort to reach the peak and respects to the deities on the highland, this scenery could not be seen in usual life on the plain.
